“…The unified BEe-RTEA treatment first proposed by Bhalla [6], as also early ESM-R-matrix investigations [64], were focused primarily on the 2p 2 1 D state, the single strong RE line seen in the 2lnlЈ Rydberg series of H-like ions [58]. Good agreement between theory and experiment was found.…”

“…3, the full R-matrix calculation shows a significant contribution from the short-range, nonresonant amplitude, not only as an increase in the overall background cross section, but also in the additional interference effect. Bhalla recognized the shortcomings of this formulation and a bit later [64] adopted the R-matrix formula- tion based on the differential scattering code of Ref. [95].…”

High-resolution doubly differential cross-section measurements and calculations for quasifree electrons elastically scattered through 180°from ground-state He-and H-like boron ions are presented. The measurements, covering the entire (for B 3+ ) and (for B 4+ ) Rydberg series populated by resonant excitation, were performed by zero-degree Auger projectile electron spectroscopy of 3.91 MeV B 4+ and 3.08-7.48 MeV B 3+ ions in collisions with H 2 targets. The projectile energy dependence study is used to further investigate other background contributions such as direct electron capture, direct excitation, and nonresonant transfer excitation. R-matrix calculations, particularly sensitive at this large scattering angle to electron correlation, exchange, and interference effects, are found to be in excellent overall agreement within the electron scattering model.

“…Note, that in present work we do not compare broad-energy-range cross sections to cross sections computed exclusively for narrow energy intervals where contributions of resonances are significant (see, e.g., Refs. [9,12,13]). Such fine detail is not necessary for the purpose of most applications.…”

We present cross sections for electron-impact-induced transitions n → n ′ in hydrogen-like ions C 5+ , N e 9+ , Al 12+ , and Ar 17+ . The cross sections are computed by Coulomb-Born with exchange and normalization (CBE) method for all transitions with n < n ′ < 7 and by convergent closecoupling (CCC) method for transitions with n < n ′ < 5 in C 5+ and Al 12+ . Cross sections 1s → 2s and 1s → 2p are presented as well. The CCC and CBE cross sections agree to better than 10% with each other and with earlier close-coupling results (available for transition 1 → 2 only). Analytical expression for n → n ′ cross sections and semiempirical formulae are discussed. PACS number(s): 34.80.Kw

“…In recent years there have been numerous studies of electron impact excitation of ions, mainly heavy (see, e.g., [1,2]). Experiments on electron impact ionization of positively charged ions have been mostly limited to total and single differential cross-section measurements (see, e.g., [3][4][5][6][7]).…”

We present triple differential cross-sections for the electron impact ionization of hydrogen and helium in energy sharing coplanar constant Θ12 = 180° and coplanar energy sharing perpendicular plane geometries at impact energies of a few eV's above ionization threshold. We investigate the role of incident channel effects in determining the shape of the cross-section. We present cross-sections in the same geometries for the isoelectronic sequence of hydrogenic and helium-like ions with nuclear charges up to Z = 10.
